Lithium Isotope Distribution Acts as Fingerprint for Battery Aging, BAM Researchers Find

Researchers at Germany's Federal Institute for Materials Research and Testing (BAM) have shown that the distribution of lithium-6 and lithium-7 isotopes inside a cell serves as a fingerprint of its degradation mechanisms. The method, published in ACS Energy Letters, could enable more targeted diagnosis and optimization of lithium-ion batteries.
